i love asking my ela teacher for work when we write essays because I never pay attention so when i ask her she literally writes the whole paper for me all i do is copy n past it on another slide and turn it in and get a 100

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
